Hello, seeking advice on putting in a new ax15 in my 87. Currently have an ax15, don’t know the year or anything about it, other than I replaced the clutch, master and slave, and oil in it recently. My synchros are going out between 3rd and 4th and when it’s hot, it either binds or grinds or doesn’t want to shift unless I manage to shift into 5th, reverse, 1st or 2nd after multiple shifts to those gears to free it up. Anyways, I’m looking for a new turn key ax15, just need to know where I can buy one ready to go with all the fix’ns on it so I can bolt it on and drive it on. I’ll eventually get around to rebuilding the old one. A neighbor of mine has an extra 4.0 he said he’s gonna give me, so I'm going to rebuild up that motor and the old trans as a project.
